Abstract
An environment plays an important role in behaviors acquisition for artificial creatures. Thus, the environment must obey the physical laws. In this paper, it is examined how the behavior differences appear when the artificial creature with wings, autonomously behaves in the air and water environment. We propose a simulation method for the artificial creature using evolutionary computation in two fluid environments with low computing cost. As a result of simulation, we verify that it is possible for the creature to acquire adaptive behaviors in different environments. After evolution, the creature behaves autonomously by leveraging effectively fluid forces in each virtual environment.
